Referring to fig. 5a and fig. 4b again, an external force F1 is applied to the slider 22, so that the slider 22 moves along the wall of the sliding slot 13 and away from the engaging slot 15, and drives the bolt 24 to move from the first position P1 to the second position P2, so that the locking portion 241 of the bolt 24 is away from the positioning hole 72a of the bolt 70.

At the same time, please refer to fig. 7a and 7b, another external force F2 is applied to the second locking element 60, so that the second locking element 60 moves from the third position P3 to the fourth position P4 inside the second receiving groove 12, and the first portion 71 of the bolt 70 is located in the second hole portion 62a of the pivot hole 60 a.

When the second latch 60 is at the fourth position P4, since the second portion 72 of the bolt 70 is no longer limited in the slot 15 by the locking portion 241 and the fifth width R5 of the first portion 71 of the bolt 70 is smaller than the second width R2, the bolt 70 can be operated to pivot along the arc surface of the second hole portion 62a of the pivot hole 60a to the open position S2 (see fig. 8).

As shown in fig. 9, since the fifth width R5 is greater than the third width R3, when the pin 70 pivots to a predetermined angle, the first portion 71 of the pin 70 abuts against the two protrusions 62, so as to limit the pivoting angle of the pin 70.

The operator can combine the body 10 with the harness and put the buckle on the safety belt on the bolt 70. Then, the bolt 70 is pivoted back to the closed position S1, after the first portion 71 of the bolt 70 leaves the hole wall of the second hole portion 62a of the pivot hole 60a, the compressed second elastic member 50 is released to push the second locking member 60 to the third position P3, so as to lock the first portion 71 of the bolt 70; the external force F1 for operating the slider 22 is removed, the compressed first elastic member 30 is released and pushes the bolt rod 24 to return to the first position P1, so that the locking portion 241 is locked in the positioning hole 72a of the bolt 70 to lock the second portion 72 of the bolt 70, and the connection between the strap and the safety belt is completed.

In addition, since the stop ring 80 is sleeved on the first portion 71 of the bolt 70, the protrusion 721 is formed at the end of the second portion 72 of the bolt 70; when the buckle connection device 100 is used, the retaining ring 80, the protrusion 721 and the buckle are respectively located at two sides of the body 10, so that when the plug 70 is pulled by an external force, the retaining ring 80 and the protrusion 721 respectively abut against the hole edge of the through hole 16 and the groove edge of the slot 15, thereby preventing the plug 70 from slipping out of the body 10.

Since the bolt 70 can be operated to pivot with respect to the body 10, when the buckle connecting device 100 is operated, the body 10 connected to the harness is not easily affected by the pivoting of the bolt 70, and the bolt 70 is not separated from the body 10 during unlocking to locking; in addition, the first locking part 20 and the second locking part 60 can be unlocked easily, and when the latch 70 is returned to the closed position S1, the first locking part 20 and the second locking part 60 automatically lock the latch 70, so that the safety belt buckle connecting device 100 can be operated easily even though an operator wears gloves.
